Insights into the mechanism of photosynthetic H 2 evolution catalyzed by a heptacoordinate cobalt complex

Lucarini, Fiorella ; Fize, Jennifer ; Morozan, Adina ; Marazzi, Marco ; Natali, Mirco ; Pastore, Mariachiara ; Artero, Vincent ; Ruggi, Albert

In: Sustainable Energy & Fuels, 2020, vol. 4, no. 2, p. 589–599

H2 evolution catalyzed by a heptacoordinate complex under both electro- (1) and photo-chemical (2) conditions is analyzed in detail in order to gain insights into the mechanism of the processes. The complex shows high catalytic activity for hydrogen production in acetonitrile, in the presence of trifluoroacetic acid and triethylammonium tetrafluoroborate as proton sources. Foot-of-the-wave...

Catalytic living ring opening metathesis polymerisation: the importance of ring strain in chain transfer agents

Liu, Peng ; Yasir, Mohammad ; Kilbinger, Andreas F. M.

In: Angewandte Chemie International Edition, 2019, vol. 58, no. 43, p. 15278–15282

A recently developed catalytic living ring opening metathesis polymerisation (ROMP) was investigated using a series of reversible chain transfer agents (CTA) carrying either cyclopentene or cyclohexene rings, differing only in ring strain. All cyclopentene derivatives examined showed significantly faster reaction rates than the corresponding cyclohexene derivatives. This resulted in lower...

Catalytic living ring-opening metathesis polymerization with Grubbs’ second- and third-generation catalysts

Yasir, Mohammad ; Liu, Peng ; Tennie, Iris K. ; Kilbinger, Andreas F. M.

In: Nature Chemistry, 2019, vol. 11, no. 5, p. 488–494

In a conventional living ring-opening metathesis polymerization (ROMP), an equal number of ruthenium complexes to the number of polymer chains synthesized are required. This can lead to high loadings of ruthenium complexes when aiming for shorter polymers. Here, a reversible chain-transfer agent was used to produce living ROMP polymers from norbornene derivatives using catalytic amounts of...

Novel iron tweezers complexes for hydrogenation and polymerization of olefins

Mafua, Roger ; Jenny, Titus A. (Dir.)

Thèse de doctorat : Université de Fribourg, 2006 ; no. 1503.

L’utilisation des complexes organométalliques comme catalyseurs est devenu un domaine très important de la chimie des matériaux. Cependant et malgré ce développement, les catalyseurs à base de fer(II) sont peu employés dans la polymérisation d’oléfines. Un de rares catalyseur utilisé dans ce contexte est le complexe tridenté diimine pyridine développé par Gibson et Brookhart....
